An important part of more modern sounding jazz solos is often the use of quartal harmony. In this lesson I am going to take 2 exercises and 5 examples of how I use quartal harmony and demonstrate how you can incorporate the sound into your own playing.
Two exercises and a II Valt I cadence
I have a few lessons on quartal harmony already that you can check out if you want to explore further into the sound both as arpeggios and chords. Here is a lesson on using the arpeggios in solos: Quartal harmony in solos
In this lesson I am first going over to simple exercises of diatonic stacks of 4ths in F major and Db melodic minor (which is the same as C altered). I am then going to use this material in the 5 examples, all on a II Valt I in F major.
Quartal arppeggios are constructed by stacking 4ths in the scale. When we build chords in a scale we ususally start with 3rds, so in F major if I start from a G. I get:
G A Bb C D E F G – so a G minor triads; G Bb D
If we use quartal harmony we stack 4ths:
G A Bb C D E F G so the stack of 4ths from G is G C F
If we use this structure as an arpeggio that we can move through the scale and play it up the neck on the D,G and B string set we get:
And using the same principle to play the diatonic stacks of 4ths in Db melodic minor:
A few of the arpeggios in the last example are a bit unusual especially the one on the 7th degree of the scale (C) which is actually a C7 shell voicing. The one on the 4th(Gb) is also a not found in the major scale version.
5 Quartal harmony licks
The first example starts with a Gm7 arpeggio and then continues into a quartal arppgegio from the D which is played in a pattern from the G. The C7alt line is based around an inversion of a Bbm7(b5) arpeggio (Check out this lesson for more ideas: The Altered Scale in Three Approaches) and then resolving scalewise down to the 5th of the Fmaj7 chord.
In the second example, here below, I am starting with a stack of 4ths from the C. You might recognize that as a fairly common Gm11 voicing. From there the line continues with a descending scale run. On the C7alt the line is starting with a trill using the #9 and the 3rd of C. From there it continues with a line derived from the Db minor triad and resolves via the #9 an octave higher to the 5th(C) of Fmaj7.
Of course we can also use the quartal arpeggios on the altered dominant since we have the material from example 2.
The third example starts with a Dm7 arpeggio that is used to target and highlight the Bb on beat 3. From there the line continues with a descending scale to the 3rd(E) of C. On the C7 we first have a stack of 4ths from the E which is infact the equivalent of a C7(#9) sound. This is a diagonal line on the fretboard and we can actually flip it around and use that as a descending pattern. On this string set that gives us a Gb major triad. This trick works really well in diminished contexts as well. The altered line is the stepwise resolved to the 3rd(A) of Fmaj7.
Another good stack of 4th idea for the C7alt is to use the one on Ab because it gives us a lot of colourful notes: Ab,Db,Gb – (b13,b9,b5).
The line the on the Gm7 is based on a Gm7 arpeggio with a scale note added here and there. On the C7alt I start with the stack of 4ths from Ab, which you could also think of as a Dbsus4 triads. The line then continues with a Bbdim triad and resolves to the 5th(C) of Fmaj7.
In the final example I am using several quartal arpeggios and also making use of that they are 3 note groups to create a cross rhythm in the line.
The example starts out with a scale run down from Bb to G. From the G and from the A we have two quartal arpeggios that work well over Gm7. Over C7 we can use two other stacks of 4ths a half step higher so from Ab and Bb. This means that I can make a pattern of three notes with the bottom notes being G, A, Ab, Bb all with 3 notes in each arpeggio. This gives us a period of 3 note groupings creating osme nice rhythmical tension on top of the meter. The line and the cross rhythm is resolved by encircling the 3rd of F chromatically and resolving on the 1.
That was a few examples of how I use quartal harmony in my playing. When you work on this you will of course get something out of checking out my lines, but don’t forget that you will probably learn more form trying to l take the concept of my examples and make your own lines combining the things you already know. That is also how I work.
